Patients 18 years of age or older with stage inflammatory breast cancer who have not been treated with chemotherapy or radiation therapy may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, chest x-ray, electrocardiogram, and MUGA scan or echocardiography (see below). A mammogram of both breasts, dynamic MRI imaging of the affected breast, computed tomography (CT) of the head, chest, abdomen and pelvis, and a bone scan are done to determine the extent of disease.
